show user profile in gridview

i do no t know why do you need that. Here is a solution of your problem. but i do not think it will be a good idea to show the user profile to a gridveiw. Cause gridview is not memory effective to display a few items.

Here is the solution. First of all gridview works with list of data. As you have one one data i guess but you also need to make a list in order to display it with gridview.

This is the method to find out the logged in user as a list:

public List<User> GetUserByUserNamePassword(string UserName,string Password)
{
  var availableUser= (from user in _DatabaseContext.Users
                    where user.FirstName == UserName && user.Password == Password
                    select user
                     ).ToList();
            return availableUser;
}

And here is the code for binding the gridview.

List<User> user = new UserBLL().GetUserByUserNamePassword("palash", "123");
if (user != null)
{
    grvUser.DataSource = user;
    grvUser.DataBind();
}

Hope it will help.
Happy coding....
